1. Nchịkwa viscosity
A na-eji hec eji eme ihe na mmiri mmiri iji gbochie viscosity. Vieocosity nke mmiri mmiri dị mkpa maka nkwusioru na ụgbọ njem nke cuttings na elu. Site na idozi ịta HEC, ndị na-arụ ọrụ nwere ike ịhazi viscosity nke mmiri mmiri iji daba n'ihe ndị a chọrọ. Njikwa a na - enyere aka ilegide arụmọrụ nke usoro igwu mmiri ma na - egbochi ihe ndị yiri ndọt nke cuttings.

2.. Njikwa Filtration
